have outer edges designed to be forced with- 1n the flanged collars 25 and 26. These plates 22 have inwardly projecting top and The edges of the lens supporting plates 18 and l9,which are adjacent the sides 8 and 9 of the box sections 2 and 3, are connected by hinges 29 and 30 to two rearwardly extending partition plates 31 and 32. These partitions, when the stereoscope is ready for use, occupy upright positionsrespectively against the sides 8 and 9 and ad' jacent their rear ends are provided with shortfianges 33 and 3st which extend trans versely'of the sections 2 and 3 and substantially parallel with the plates 18' and 19 when the latter are in their upri ht posi- The plates 31 and 32 have narrow tongues 35 and 36 which are located adjacent said sides 8 and 9 of the box sections 2 and 3 (see Figs. 1, 3, 4, and 9). Each of the tongues 35 and 36 is provided with an elongated slot 37 which registers with slots 38 and 39 which are respectively cut in the sides 8 and 9 of the box (see Figs. 1 and. 4:).

A resilient finger 4C0 is secured to the inner surface of the side 8 by means of a rivet ll or other suitable means and has its free end 42 linked to a binding or locking pin l3, the latter being designed to be projected through the slots 37, 38, and 39 when the box sections 2 and 3 are opened and is provided at its-free end with an eye 4:42 into which extends the end of hook 45, the latter being pivoted at 16 to the, inner surfaceof the side 9 of the box section 3, so that when said hook 45 engages the eye 44-, the box sections 2 and 3' will be held in an open or spread position with'their sides 8 and 9 engaging and it'willbe impossible to close said sections until the hook 45 is removed from the eye 44, and the pin l3 withdrawn from the slots 37 to 39 inclusive. j I It will be of course understood that the pin4c3' is made of a predetermined length according to the thicknesses of the different members through which it. is projected, so that the hook'4-5 will really act to' place a slight tension on the pin to prevent the parts from accidentally loosening.

For convenience .of description, the portions 47 and 418 of the box sections 2 and 3 will be termed the bottom and top, but it will be understood that whensaid sections are folded and since they are. of substantially the same construction, there will be practically no top or bottom.

v The portions l7 and 48 have openings l9 and50 which are designed to receive handles 51 and 52, and these openings are preferably eas es made of the same contour as the handles as clearly shown in the drawings. The openings 49 and 50 are extended part way through the sides 8 and 9 as clearly shown in Fig. 8.

Each of the handles 51 and 52 is provided with an ear 53 which extends at right angles thereto as clearly shown in Fig. 6. These handles are hinged to the box sections at 54, so that when the handles are in a pendant position as shown in Figs. 2 and 9, the ears 53 will be in the same plane with the portions 47 and 18 of the-box sections 2 and 3, and will lie directly under the partition plates 31 and 32, and since the latter are held rigidly in their upright positions by the locking pin 13 as above mentioned, the handles 51' and 52 will be locked in said pendant position and cannot move-on their p'vots until the partition plates 31 and 32 are moved on their hinges 29 and 30 toward the lens supportinf plates 18 and 19'so to free the ears 53 and permit the handles 51 and 52 to be turned on their pivots.

The handles 51 and 52 are locked in their positions within the openings l9 and 50 in the following manner :After the partition plates 31 and 32 are moved on their hinges 29 and 30 toward the lens supporting plates 18 and 19, the latter are folded downwardly into the box sections 2 and 3 as shown in the dot-and-dash position in Fig. 3, it being understood that when the handles '51 and are within the openings 19 and 50, the ears 53 will be in position within the extensions of the openings 19 and 50 in the sides 8 and 9 as clearly shown in Fig. 8. Therefore, when the lens supporting plates 18 and 19 and the partition plates 31 and 32 are folded into the sections, the ears 53 will be confined between the hinged edges of said latter plates and the sides 8 and 9. In other words, the lens supporting plates and the partition plates act as a stop to prevent movement of the handles on their hinges and said handles are thereby locked.

An object holder '55 is preferably made of pressed sheet metal and formed into a frame as clearly snown in Fig. 9. The frame consists of a back 56 having forwardly projecting end portions 57 and 58. The end portions have flanges 59 and a bottom 60 ias a front flange 61. This frame is especially adapted for holding cards, pictures or other objects to be viewed, the flanges 59 and 61 and the back 56 tending to confine the cards in a position to be properly viewed through the lenses 2 1. c

The bottom 60 is slit to provide a clip 62, said clip consisting of downwardly extendingportions 63 which are spaced apart and designed to straddle the hinged sides 8 and 9 of the box sections 2 and 3 to slide longitudinally thereon.

Lips Glare hinged at 65 to opposite ends 57 and 58 of the object h'ol'der55, and are designed to engageunderthe longitudinally extend ng flanges 5. The lips =64 have in? wardly projecting extensions '66 designed to abut the under surface of the b'ottom'GO, and said lips are so located that they-triotionally engage the under surfaces "of the flanges (Sand 7 to provide a steady support for theholder.

I A handle 67 is provided on the holder 55 and in the present instance consists of a loop of wire which has eyes in. its YGHClS pivotally hung on trunnions 69. The handle 67 facilitates the movement of the holder longitudinally of the box sections toward and from the lenses 2% to secure the desired focus. I

A detachable. spring 70 has-a hooked end 71 designed to engage the upper edge ofthe back '56,-the portion 72 of the spring'being bent forwardly and designed to keep pic tures or cards which are placed within the holder against the flanges '59 and '61, however, if the holder is entirely filled with pictures or cardsythe spring 7 0 maybe re-v moved by raising the hooked end 71. It will thus be noted that when only a few cards are positioned within the holder, the spring 70 acts to hold them in an upright position against the flanges 59 and 6 In the use of stereoscopes, two pictures of the object or scene to be viewed are usually provided, one'on each side of a vertical center line on the cards containing the pictures, and since'the pictures are viewed by both eyes, means is generally provided to obscure the direct dividing line from the vision so that :the pictures will appearas a unitary picture to the observer. I no complish this end by the provision of the flanges 33 and 34: on the inner ends of the partition plates 31 and 32.

When not in use, the lens supporting plates and partition plates are folded into the box sections as above described, and the holder 55 may be removed by sliding it into register with thenotches 6*" and 7 in the flanges 6 and 7, when it may be lifted bodily, the lips 6 passing out through said notches. Aftertheholder has been thus removed, it can be-placed within the box sections, it being of course understood that the handle sections are moved into the openings 49 and 50 as above described. The box sections 2 and 3 may then be closed and locked in a closed position. by any suitable clamping means.

In the form of my invention shown in Figs. 10 and 111, I have shown a modified form of box in which. sections 73 and :74 are hinged together at 75 and 76 respectively. The sides 77 and 78 are flanged longitudinally at 79 and 80 and are similar to the flanges 6 and 7 above described in connection with the box sections 2 and In this modification of my invention, the portionfilprovides one side of the box when the latteris folded, and when in its/openposition a slot 82 therein forms a guidewaylt'or "depending ITLGHlbGISB in an object holder Sl, the latter is of the samei'general construction Lthe objectholder 155 above described with the exception of the construction ofitSlips 85 which are hinged to'the sides thereof and extensions 86 thereon are substantially at right angles to engage the endsof the holder. In-this construction, the'holder 84 is slidable :alongthe surtaces 87 and '88,an'd the extensions 86 of the lips 85 serve to hold the holder-in position and also serve to hold the box sections in their extended po? sition, since it is impossible to remove the holder until the M13385 are manually/removed from under the flanges 79 and 80.

In Fig. :12 I have shown a modification of the structure shown in Fig. 8, but'i-nstead of having-the openings 4:9 and 5O-extend into the sides 8 and 9, they terminate short ofsaid sides, and theears 53 of thehandles 51 and 52 engage the inner surfacesofthe sides 8 and '9- whensaid handles are moved into the openings 49 and 50. The position oi": the ears 53, when the handles 51 and 52 are within the openings 49. and .50, are shown in -dot-ai1ddash lines in engagement with the inner surf-aces of said sides 8 and 9. I My invention is of particular value to travelers, business men, and salesmen, but it will be understood that it may be used advantageously by any one who desires a stereoscope which may be conveniently ear ried in the pocket and which will be com pact, durable, and require but little-space tocarry it. In certain of the claims I have used the term a box of fixed length by which is implied a box whose length is not altered, but on the contrary is the same both-when the box is closed and open ready forms, the length of the box being considered as the distance between therear end adjacent the object holder and the front end which is adjacentthe front of. the'lenses.

While I have described myinvention as taking auparticular form, it will be understoodthat the various parts of my invention may be changed without departing from. the spirit thereof, and henceI do notlimit myself to the precise constructionset forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.
